y v Application led December 19, 191'?.` Serial 110.207,809;

l'cisco and'Sta-te of California, have invented new and usefulImprovements in Liquid- Meters, of wlich the following is aspeclflcation. I

The object of the present invention" is to provide a simple,inexpensive, compact 'and' accurate means for reglsterlng'the maghi`tude of the flow of the flowing l1qu1d,'wh1ch is adapted for measuringthe ow of liquids of all kinds In the accompanying drawing, Figure is aplan view of a box-like casin of my nn"- `proved liquid meter, the "mecanisln non. mally therein beingy removed; Fig. 2 1s a broken plan viewshowing` said parts partly in, section; Fig. 3 is a view 'slmllar toFig. 2 showing said parts'in the same manner but in positions differentfrom thosein Fig. 2

Fig.` 4 is a transverse .vertical section through the meter.; Fig. 5 abroken plan. v1ew thereof.

Referring to the'. drawing, l1 indicates a i base to which is bolted thelower portion 2 of a casting,` the upper portion of which is in the formof a rectangular box 3, the top of whichbox is closed by a removablecover -4 bolted down thereon tight,- and inclosing therewithin arectangular hard rubber slide piece 6. Said slide piece 6 consists offour walls, of which two, 7, are longer than the 'other two, 8, and fitclosely against the long ,and an'outlet pipe `12. The conduit 9 disasshown at .'13, in the 'charges centrallgt ox-shaped portlon of thebottom of the casting, while the conduit 12. opens in the bottom of saidbox-shaped portion at a distancey from the center, and communicates witha circular groove 414 formed in the bottom`- of said box-shaped|portion.

`Slidable in said box-shaped part 3 of the ,casting is a hard rubbermeter-head 15 which is likewiserectangulanin form and of a length to fitexactly between the end -walls 8 of the slide' piece 6. The width,

u however, of said meter-heady is less than the width of the slide toenable it to slide transversel in the slideV iece 6. The meter-headbottom of the box 3 and the under surface of the cover 4. Centrall intheunder-side ofthe cover is a cylin rical recess 16 in which' is fitteda disk .17, from the center of 'which a shaft 18 extends upwardlythrough a bearing 19in the cover, a hard rubber bushin 20 beinginterposed between. the shaft and lts bearin From the disk depenl seccentrically a pin 21 which passes throu h a central hole in themeter-head. It is evi ent that, if the meterhead is given a 'motion ofrevolution about thecenter of the disk, the shaft 18 will be rotated. l

The meter-head is formed with four equally spaced conduits 22. Eachconduit' leads from the bottom of the meter-head first directly upwardand then outward in a spiraldirection, the spiral portions 23 of lsaidconl duits Increasing in width outwardly and ter minating in themiddleof the sides -of the meter-head. The length of the spiral is such thatthe conduit turns through a right angle from its beginning inlet end 'ofeach conduit lies directly between the center of the meter-head and oneof its straight sides and 4the conduit termi; nates in the'middleofaside which is next adjacent to the aforesaid side. By reason of theeccentric relation of the pin 21 and the shaft 18, the meter-head willalways be eccentric to said shaft 18, 4and the smaller to its end. The 1end of one conduit 22 will always be in registerwth a-portion of thegroove 14 whl `the smaller end of the opposite conduit 22 will alwaysbein register with the one-half of the-.hole 13 which is farthest fromsaid portion of the groove 14. supposing the. parts to bein the positionin which the entrance or narrow end of one of the conduits 22 is'nearest a long Vside of the" slide piece 6, thenthe liquid will flowthrough hole 13 into the smaller end of one of said conduits 2 2 andwill iow outward in said l` conduit 22 to the outer end thereof, thenico =the inlet pipe 11 and inlet conduit 9 and site end of the boxthrough the corres onding )ort 24 in the adjacent wall 8 an into thelarger end of the spiral portion 23 of the opposite conduit 22 and outthrough the smaller end thereof and into the groove 14 and ,so into theexhaust pipe-12. By the pressu e of the liquid the slide piece is movedfrom't rst-named end toward the secondnamed end.

The meter-'head is also moved with the slide frame in a longitudinaldirection, and by'reason of the 'fact that this motion is controlled bythe pin 21 which enters the central hole in the meter head, it. cannotmove in a straight line in a longitudinaldirection, but must move alsoin a transverse direction, and thus a circular motion is imparted to thecenter of the meter-head,

which .causes the communications between the first-named pair ofconduits 22and the hole 13 and groove 14 respectively to be diminished,and communications to beopened and enlarged between said hole 13 andgroove 14 and the other pair of said -conduits 22', so that pressureliquid is now flowing from the hole 13 into both of the smaller ends ofsaid conduits 22, and liquid is flowing from the smaller ends of theopposite conduits 22 to the groove 14:. Part of the pressure liquid nowlows through one of the other conduits 22 and imparts pressure in aftransverse direction against one of the longitudinal walls of the meteryhead, and, conversely, liquid from the opposite side of said meter-headflows inwardly vthrough the .spiral conduit 22 into the.

groove 14' and discharges, outwardly. vThe meter-head -is thus pressedin a transiferse direction so that when liquid flows from: the hole 13through twovadjaceut short ends of the conduits, vpart of the How ofliquid has the effect of pushing the meter-head transversel and part hasthe electof-pushing the sllde frame longitudinally, in all cases,however, giving to the meter-head a lcircular motion' of revolutionabout the shaft 18. 'It will be seen Ethat in this way a constantrotation is imparted to said shaft. The long sides 7 of thes'lide piece6 are cut away at top and bottom, as shown at 25, to reduce their heightto. less than vthat of the `outer ends of the conduits 22.

so that the liquid is in contact with the ad-l jacent walls of the box3.

This motion of rotation of said shaft may be utilized in any mannerlto'deter'mine the; rate of flow of the fluid-.in ythe meter.Foryinstance,as `shown inl Fig. 5,-5the Shaft 18 may carry a staple 26which meshes with a gear wheel 27 upon va shaft 28 carrying also aspiral gear wheel 29 which meshes with a spiral gear wheel 31 on a shaft32 ,which actuates mechanism 33 for registering the amount of liquidpassed through the meter.
